DDA/Accessibility Testing

Under the Disability Discrimination Act (DDA) 1995, accessibility is a legal requirement in the UK. When interpreted for IT systems, the act places obligations on organisations to ensure that websites, web- and other GUI-based applications are accessible to people with disabilities, whether in-house staff or external customers or users.

This testing therefore evaluates the compliance of the system with the Disability Discrimination Act (DDA) and the ease of access for users with disabilities. Our testing primarily covers web applications and considers aspects of the system such as:

  • Ease of site navigation including whether navigable by keyboard only
  • Use of tables, frames and other page structures and the compatibility with screen-reading software
  • Use of colour, contrast and text size combinations and the consequent accessibility for users with impaired vision
  • Deployment of additional textual aids for users of screen readers
  • Extent of use of java and other types of client-side scripting
  • General compliance with W3C standards

We use a combination of manual HTML inspection, automated script checking tools, screen-reading tools and similar utilities to inspect the system's GUI. Based on this approach we are able to recommend ways that the system can be made more accessible.
